protection
Motor overload protection
Power source voltage is too low
General motor run at low
speed with big load
Motor overload protection factor set
incorrectly
Motor blocked up or load change
too suddenly and quickly
The operating current of inverter
less than underload threshold
load divorced from motor
The three-phase input power supply
is abnormal
Power supply board anomaly
The control board anomaly
When the motor runs inverter three-

phase
Air-path blocked or fan damaged
Ambient temperature is too high
7. Troubleshooting
Adjust V/F curve and torque boost
check power source voltage
Can choose frequency conversion
motor for long time low speed run
to set motor overload protection
factor correctly
Check the load
Confirm whether the parameters F19.08,
F19.09 setting are reasonable
Checking whether the load divorced from
motor
Check the three-phase input power line is
off or poor contact
Look for service from manufacturer or
